Water Test Results

Over the past year, the Clean Power Coalition’s Data Committee has engaged in two rounds of water testing of creeks, streams, and marshes near We Energies’ Oak Creek coal plants. We have publicly released the test results of three locations; a culvert on the south side of the plant near 7 Mile Road, a stream that crosses Highway 32 near the intersection of the bike path, and a marsh along County Line Road. A few additional sites were tested but did not produce any concerning results. UW-Parkside students helped with the sampling to make sure proper protocol was followed. 

As shown in the table below, a variety of toxic heavy metals exceeding Wisconsin’s public health standards were found in these samples, including high levels of manganese and boron, which can be indicators of coal ash contamination. Thus, we are calling on the Wisconsin Department of Natural Resources to investigate this matter further and conduct independent testing in surface waters around the coal-burning facility. We will be bringing these test results to share with DNR officials at the public hearing for We Energies’ water discharge permit on February 11th, 2019, at 1 p.m. The hearing is at the Oak Creek Community Center, 8580 S Howell Ave, Oak Creek, WI 53154. We encourage interested members of the public to join us at this hearing.
